Abstract

A measuring head is adjustably mounted on a stand and includes a resonantly vibrating sensor (6) which combines with the oedema to form a resonance system when it is placed against the oedema to a given depth. A means is provided for reading the actual vibration frequency of the sensor and a means (5) is included for measuring the force with which the sensor is applied to the oedema.
